摘　　要：在国家大力推动省间电力市场建设的背景下,多个购电省共同参与省间电力现货市场时存在竞争关系。为了给购电省制定合理的报价策略,提出面向省间电力现货市场的购电博弈竞价模型。首先,根据购电省省内市场运营情况计算边际省间购电量-价曲线,以此作为购电省参与省间电力现货市场的报价曲线。然后,提出联络线潮流方向可变场景下省间电力现货市场出清与定价模型,并建立多个购电省参与下的省间市场非合作博弈竞价模型,所得纳什均衡下的报价曲线即为购电省最优购电报价。最后,构建包含2个售电省和3个购电省的算例系统进行仿真计算,验证了所提模型的有效性,并获得了购电博弈竞价模型的纳什均衡解。In the context of China’s vigorous promotion of inter-provincial electricity market construction,there ex⁃ists a competitive dynamic among multiple purchasing provinces participating in the inter-provincial electricity spot market.To devise a rational bidding strategy for these purchasing provinces,a game bidding model for electricity purchasing tailored to the inter-provincial electricity spot market is proposed.Firstly,the marginal inter-provincial electricity purchase quantity-price curve is calculated based on the operational conditions of the electricity market within each province,serving as the bidding curve for its participation in the inter-provincial electricity spot market.Subsequently,a model for market clearance and pricing in the inter-provincial electricity spot market is proposed under the scenario of variable flow directions of tie-lines.A non-cooperative game bidding model for the interprovincial market,involving multiple purchasing provinces,is established,where the bidding curve obtained under Nash equilibrium represents the optimal electricity purchase bid for the purchasing provinces.Finally,a simulation calculation is conducted on a case study system comprising two selling provinces and three purchasing provinces to validate the effectiveness of the proposed model and obtain the Nash equilibrium solution of the bidding model for electricity purchase.
